Fibrillin proteins are major structural components of the 10-nm microfibrils found in elastic and nonelastic connective tissues. Previous studies have mapped the human genes for two fibrillins to chromosome bands 15q21 (FBN1) and 5q23-q31 (FBN2) and have demonstrated that FBN1 mutations are associated with Marfan syndrome, while FBN2 is linked to the gene for congenital contractural arachnodactyly. Here, we report the isolation of genomic clones of the corresponding mouse fibrillin genes (Fbn-1 and Fbn-2). By analyzing a mapping panel of mouse x rodent somatic hybrid cell lines, we have assigned the Fbn-1 gene to mouse chromosome 2 and the Fbn-2 gene to mouse chromosome 18. We then sublocalized the fibrillin genes to bands 2F (Fbn-1) and 18D-E1 (Fbn-2) by fluorescence in situ hybridization. These regions are known to exhibit conserved synteny with the regions on human chromosomes 15 and 5 that carry the homologous human fibrillin genes. In addition, the Fbn-1 gene maps in the vicinity of the gene for a connective tissue disorder on mouse chromosome 2 called Tight-skin (Tsk).
